remain icy when the surrounding roads are clear. If
you see a patch of ice ahead of you, brake before you
are on it. Try not to brake while you’re actually on
the ice, and avoid sudden steering maneuvers.
If You’re Caught in a Blizzard
If you are stopped by heavy snow, you could be in a
serious situation. You should probably stay with your
vehicle unless you know for sure that you are near help
and you can hike through the snow. Here are some
things to do to summon help and keep yourself and your
passengers .safe: Turn on your hazard flashers. Tie a red cloth to your vehicle to alert police that you’ve been
stopped by the snow. Put on extra clothing
or wrap a
blanket around you.
If you have no blankets or extra
clothing, make body insulators from newspapers, burlap
bags, rags, flsor mats
-- anything you can wrap around
yourself
or tuck under your clothing to keep warm. I
You can run the engine to keep warm, but be careful.

A CAUTION:
dnow can trap exhaust gases under your vehicle
This can cause deadly
CO (carbon monoxide)
gas to get inside. CO could overcome you and
kill you. You can’t see
it or smell it, so you might
not know
it is in your vehicle. Clear away snow
from around the base of your vehicle, especia”--
any that
is blocking your exhaust pipe. And
check around again from time to time to be’su
snow doesn’t collect there.

Passing
You’ll need more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal \
longer, you’ll need to go much farther beyond the
passed vehicle before you can return to your lane.
d
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer to the left, just move that hand
to the left. To move the trailer to the right, move your
hand to the right. Always. back up slowly and, if
possible, have someone guide you.
Making Turns
When you’re turning with a trailer, make wider turns
than normal.
Do this so your trailer won’t strike soft
shoulders, curbs, road signs, trees, or other objects.
Avoid jerky or sudden maneuvers. Signal well in
advance.
nrn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have a
different turn signal flasher and extra wiring. The green
arrows on your instrument panel will flash whenever you signal a turn or lane change. Properly hooked up, the trailer lights will also flash, telling other drivers
you’re about to turn, change lanes or stop.
When towing a trailer, the green arrows on your
instrument panel will flash for turns even if the bulbs on
the trailer are burned out. Thus, you may think drivers
behind you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down a long
or steep downgrade. If you don’t shift
down, you might have to use your’brakes
so much that
they would get hot and no longer work well.
On a long uphill grade, use the highest gear. possible. If
you cannot maintain posted speeds, driving at a lower
speed may help avoid overheating your engine and
transaxle.
Parking on Hills
You really should not park your vehicle, with a trailer
attached, on a hill. If something goes wrong, your rig
could
start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
183

But if you ever have to park your rig on a hill, here’s
, how to do it:
1 1. Apply your regular brakes, but don’t shift into.“P”
I (Park) yet.
I 2. Have someone place chocks under.the trailer wheels.

Maintenance When Trailer Towing
Your vehicle will need service more often when you’re
pulling a trailer. See the Maintenance Schedule for more
on this. Things that are especially important in trailer
operation are automatic transaxle fluid (don’t overfill),
engine oil, belt, cooling system, and brake adjustment.
Each of these is covered in this manual, and the Index
will help you find them quickly.
If you’re trailering, it’s
a good idea to review these sections before
you start
your trip.
Check periodically to see that all hitch nuts and bolts are
tight.
I 1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
0 Shift into a gear; and
0 Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.

Before you connect the cables, here are some things
you should know. Positive (+ ) will go to positive (+)
and negative (-) will go to negative (-) or a metal
engine part. Don't connect
(+) to (-) or you'll get a
short that would damage the battery and maybe other
parts, too.
I
5. Check that the jumper cables don't have loose or
missing insulation. If they do, you could get a shock.
The vehicles could
be damaged, too.

A CAUTION:
I
An electric fan under the hood can start up even
when the engine is not running and can injure
you. Keep hands, clothing and tools away from
any underhood electric fan.
If the coolant inside the coolant surge tank is boiling,
don’t
do anything else until it cools down.
The coolant level should be at or above
“FULL COLD.”
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water pump or somewhere else in
the cooling system.
A CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them. If you
do, you can be burned.
Don’t run the engine if there is a leak. If you run
-le engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Nt any leak fixed before you drive the vehicle.
If there seems to be no leak, check to see if the electric
engine fan is running.
If the engine is overheating, the
fan should be running.
If it isn’t, your vehicle needs
service.

Engine Oil
It's a good idea to check your engine oil every time you
get fuel.
In order to get an accurate reading, the oil must
be warm and the vehicle must be
on level ground.
1
I
The engine oil dipstick is located directly behind the
engine fan.
Turn
off the engine and give the oil a few minutes to get
back down into the oil pan.
If you don't, the oil dipstick
might not show the actual level.
223

To Check Engine Oil: Pull out the dipstick and clean it
with a paper towel
or cloth, then push it back in all the
way. Remove it again, keeping the tip lower.
When to Add Oil: If the oil is at or below the upper
mark, then you’ll need
to add some oil. But you must
use the right kind,. This section explains what kind of oil
to use. For crankcase capacity, see “Capacities and Specifications” in the Index.

Wait at least 30 minutes before checking the transaxle
fluid level if you have been driving:
When outside temperatures are above 90 ’ F (32 ’ C).
0 At high speed .for quite a while.
In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is 180’F to 200’F (82OC
Get the vehicle warmed up by driving about
15 miles
(24 km) when outside temperatures are above 50’F
(1 0 C). If it’s colder than 50 OF (10 ’ C), you may have
to drive longer.
To’check the fluid level:

Park your vehicle on
a level place.
Place the
shift lever in “F”’ (Park) with the parking
brake applied.
With your foot on the brake pedal, move the shift
lever through each gear range, pausing for about
three seconds
in each range. Then, position the shift
lever
in “P,’ (Park).
Let the engine
run at idle far three to five minutes. Then; without shutting off the engine, follow these
steps:
.I. Pull out the dipstick and wipe it with a clean rag or
paper towel.
2. . Push it back in all the way, wait three seconds and
then pull it back out again.
